driving to elevation after diving?

Given the info provided, you will be courting no additional risk.

In my Newbie Opinion:

Dive planning should extend to the day(s) prior to the dive and the trip home afterward. Thanks
Knotical for the link to the tables. I too make dives where I have to drive a mountain pass on the way home and will be carrying those tables alongside my RDP.

Some of the responses to this question trouble me somewhat. I crossed the street 3 times against a red light and didn't get hit so you should be able to as well.........

This is just my personal opinion.

Dive Safe.

Hehe. My newbie opinion too.

There is another thread about this somewhere on the forum I think, unless it was deleted in the crash..
It was basically going the same way this one is going, no common consensus wether you should wait or not IIRC.
My problem at one of my locations is that if I dive, doff, stow gear and drive, ill be going from 250 feet to almost 3000 feet within the first 5 minutes after getting into the car, Maybe as little as 10-15 minutes after getting out of the water.. (Yeap, its steep hills there)

That's certainly a reasonable concern.

I would like to add that my response had lots of thought going on behind it - it was essentially a summary without all the wordy stuff.

Some of the science behind my answer:

>The NOAA Ascent to Altitude Tables
>The Bell/Borgwardt CAR (California Ascent Rate) study
>Doppler bubble studies regarding altitude diving and ascending after diving with myself as one of the test subjects
>and a couple hundred dives doing more than what the OP proposed

All the best, James

I'd feel pretty safe going to those elevations (not altitudes... you're driving). However we had an instructor get bent after a series of pretty conservative dives. She drove to an elevation of 1,600 feet to get to her BF's house after diving. I'm just glad my house is only about 200 ft above sea level.

Makes me all the more convinced that I should stop by the local burger shop and have a big fat burger before I go home from previously mentioned divesite then.. Ahh, its good to get excuses like that to pay others to make my food...

The lake we routinely dive here is at 5250 ft. I wouldn't be concerned with gaining 600-800 feet elevation.

I agree with Crowley.

NOAA addresses the issue.
http://www.ndc.noaa.gov/pdfs/AscentToAltitudeTable.pdf

Note that they don’t require a surface interval unless you are ascending at least 1000 feet.

caveat: To take full advantage of the NOAA table, you’d need to use their pressure groups from their dive tables:
http://www.ndc.noaa.gov/pdfs/NoDecoAirDiveTable.pdf
http://www.ndc.noaa.gov/pdfs/ResidNitroTable.pdf

Note also that recent DAN guidelines imply that elevations of 2000 feet and below are not worrisome:
From: http://www.diversalertnetwork.org/ne...asp?newsid=258
“The following recommendations . . . . apply to air dives followed by flights at cabin altitudes of 2,000 to 8,000 feet.”

Waiting before ascending to the moderate elevation you describe is very conservative. I’d consider disassembling my gear and packing it in the car a sufficient wait.

OK, I give up. How do you use the NOAA tables for mutiple dives?

...the same way you'd use conventional tables for multiple dives?

<shrugs>

If you are asking specifically about the Ascent to Altitude tables, you use the highest Repetitive Group (in the last 24 hours) for computation of your SI until moving to the higher altitude.


All the best, James
